Hi Jordan.
Thanks for your comments. Much appreciated.
Your observations are on the mark. The paint on both attempts went down in a fine spatter. The Mineral Spirits has a very slow evaporation rate and the test board was still wet after six hours in the house and did not dry to the touch for about 16 hours. When dry, it indeed feels like fine sandpaper.
I was hoping to avoid hauling out my main spray gun setup from the basement out to the garage to work this all out but that is clearly in the cards now. Wind, dust, bugs and a long walk to the house are not my friends and it is shaping up to be a stinky hot weekend here.
My gut tells me the 4:1 mix ratio of paint to thinner is probably correct. The little Preval system could just not deliver the paint. So, I shall start another test, weather permitting next weekend at 4:1, with the compressor at 40 psi, which will provide a proper air volume. If the paint flows well I will move directly to the required finish work. If it still spatters, I will try a remix at 3:1 and see what happens.
Must say I am not fond of working with the mineral spirits, turpentine and varsol family of thinners any more. They take forever to dry and always seem to leave a greasy feeling residue.
Also miss my old spray gun outfit. I had two paint canisters for it and a canister cap so I could have one on standby with thinner for a quick clean of the gun and I could also cap a mixed canister of paint for a while if I needed to do so.
CH seems to have outsourced their parts operation in the USA to several third party dealers and here in Canada I could get a second canister from Grainger, but canister caps no longer appear to be available. Better start raiding Debs stash of jam jar lids to see if one will fit.
I will post again after the weekend, if my sanity allows. Thanks again,
David
